Research on biological control agents against weeds in winter rainfall pastures has been conducted since the 1920s.CSTRO Division of Entomology, Canberra, and the Keith Turnbull Research Institute, Victoria, have been the main introduction centres. Agents are selected to attack critical parts of the weed's life cycle and reduceitsvigour, density and economiccostto the pasture industry.Some introduced agents arenotreleased fromquarantinebecausethey arefound tobenot target-specific.Ofthose released, some may fail to establish or, if they establish, may not exert any control over the targetweed, In othercases,they maybe successful on their own,butoften formpartofa weed managementstrategy involving chemical herbicides, tactical grazing and other methods. This chapter includes weeds of winter pastures on which imported biological control agents exert at least some control.
